It’s the second-spookiest day of the year, so let’s cap off the week with a little murder. Friday the 13th: Killer Puzzle is a light, silly, mostly-free and utterly gore-drenched spinoff from Blue Wizard Digital’s Slayaway Camp, a simple block-sliding puzzle dressed up as a slasher horror splatter-rampage. This time, you get to play as everyone’s favourite ultra-zombie, Jason Voorhees. He’s a good boy, really – listens to everything his mum tells him.
